Witryna13 wrz 2024 · In this study, we designed a framework in which three techniques—classification tree, association rules analysis (ASA), and the naïve Bayes classifier—were combined to improve the performance of the latter. A classification tree was used to discretize quantitative predictors into categories and ASA was used to … WitrynaScikit Learn - Multinomial Naïve Bayes. It is another useful Naïve Bayes classifier. It assumes that the features are drawn from a simple Multinomial distribution. The Scikit-learn provides sklearn.naive_bayes.MultinomialNB to implement the Multinomial Naïve Bayes algorithm for classification.
Witryna1 Answer. Bernoulli models the presence/absence of a feature. Multinomial models the number of counts of a feature. Here's a concise explanation. Note that a naive Bayes … Witryna"""The Complement Naive Bayes classifier described in Rennie et al. (2003). The Complement Naive Bayes classifier was designed to correct the "severe: assumptions" made by the standard Multinomial Naive Bayes classifier. It is: particularly suited for imbalanced data sets.
